Improvement in ash-sifters



UNITED STATES PATENT OFFICE.

ALGAE FENNER, .OF ROCHESTER, NEW YORK, ASSIGNOB OF ONE-HALF HIS RIGHT TO DAVID GLANGY, OF SAME PLACE.

IMPROVEM ENT IN ASH-SIFTERS.

Specificationforming part of Letters Patent No. 214,997, dated May 6, 1879 application filed January 17, 1879.

To all whom it may concern.-

Be it known that I, ALGAR FENNER, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Ash-Sifters, which Improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a plan view, having the cover partially broken away; Fig. 2, a side sectional elevation, and Fig. 3 an end elevation.

My invention relates to that class of ashsifters in which the sieve-tray containing the material to be sifted is placed within a closed box or body mounted upon rockers; and it consists in the construction and arrangement of certain parts, which will, after the following description, be specified in the claim.

In the drawings, A is the body of the sifter, mounted upon rockers D, covered by a lid, B, and having handles d; and O, a removable sieve-tray, fitted within the body and resting upon ledges c. The end boards a a of the body are vertical, and of uniform thickness, while the end boards I) b are tapering as to thickness and obliquely placed, as shown. The thick edges of the boards I) I), placed con tiguous to the boards a a, are slightly thicker than the latter, and, being placed even on the outside, form upon the inside shoulders or ledges, upon which to rest the sieve-tray C, while the thin edges of the said boards correspond in thickness to the boards a a. and other parts of the body A.

In manufacturing these ash-sitters I cut the boards b b from a plank of rhomboidal crosssection, the form of cross-section being indicated by the additional dotted lines 71., by sawing through obliquely on the line 0, which forms both pieces I) b (one in full lines and the other in dotted lines) alike.

This manner of construction of the ends of the body I find to be of great advantage in practice, for otherwise separate pieces or cleats would have to be formed and fastened in place for supporting the sieve-tray, which would add to the number of pieces used in the construction of the sitters, to the labor, and to the material consumed.

The ledges c are narrower than the end boards, e, of the sieve-tray, thus forming no obstruction to the ashes as they fall through the grate 8, allowing a clear fall to the same from all parts of the sieve into the ash-space S, which is an advantage over some other sitters as constructed, in which the fall of the ashes is thus obstructed.

The bottom board, 9, of the body is made to slide eudwise and allow the ashes to be discharged from the body without having to invert the same for that purpose.

I am aware that ash-sitters have before been made with a body resting upon rockers and containing a sifting-tray-as, for instance, that shown in Patent No. 141,737.

I am also aware that sliding bottoms have been employed, as in Patent No. 59,927, and also that a ledge formed by a strip has been used for the tray to rest upon, as in Patent No. 207 ,948.

What I claim as my invention, and wish to secure by Letters Patent, is

An ash-sitter having side rockers, D, a sliding bottom board, g, between the same, and elevated, as shown, so as to leave a space below its supports for the ashes when it is with drawn, the vertical upper end boards, a, and straight inclined lower end boards, 0, and with ledge c at the juncture of the said straight inclined and the vertical boards, for the tray to rest on, the whole constructed and arranged as shown and described.

ALGAR FENNER.
